Module version

The Unix epoch timestamp (in milliseconds) at which this build was produced, written by src/buildjs/makever.cjs. Useful for distinguishing builds with the same version string during development, and for diagnostic logs.

The published semantic version of the jssm package this build was cut from. Mirrored from package.json by src/buildjs/makever.cjs at build time. Useful for runtime diagnostics and for embedding in serialized machine snapshots so that deserializers can detect version-skew.
